COPYING-PRESS.

SPECIFICATION forming part of Letters Patent No. 616,745, dated December27, 1898.

Application filed March 16, 1898- Serial No. 674,06. (N model.)

T0 at whom it may concern:

Be it known that I, OSCAR J. TAEUBER, of La Crosse, in the county of LaCrosse and State of \Visconsin, have invented a new and ImprovedCopying-Press, of which the following is a full, clear, and exactdescription.

This invention is a copying-press of that class in which thecopying-paper is in the form of a web wound upon a roll and carried in acasing, the paper being drawn from the roll and through a wet device bymeans of yielding rollers which press the paper against the original andeffect the reproduction.

This specification is the disclosure of one form of my invention, whilethe claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of the invention. Fig. 2 is a plan viewthereof with the top plate removed. Fig. 3 is a vertical longitudinalsection.- Fig. 4 is a fragmentary view of the cutting apparatus. Fig. 5is a section on the line 5 5 of Fig. 4. Fig. 6 is a perspective view ofthe block employed to separate the wet copying-paper from the rolls, andFig. 7 is a perspective view of a funnel useful in filling the wettingapparatus.

The copying-press is mounted on a heavy base 8, having a plate 9 securedthereto, on

which stand the two skeleton-like standards the standards 10 andbearing, when in closed position, against a stop-bar 13, which also runsbetween the standards 10 and forms a brace therefor. The plate 11 isprovided with a hinged limb 14, which is adapted to engage one of thestandards 10, as shown by dotted lines in Fig. 3, to hold the plate 11in horizontal position, in which position the plate is arranged duringthe copying operation to form a table for the support of letters andother papers. When the plate 11 is moved downward into closed position,the limb 14: swings into a recess 15 formed in the plate, as alsoindicated by dotted lines'in Fig. 3, in which position the limb is heldflush with the inner face of the plate. The top plate 16 of the press isprovided at each side edge with lugs 17, that fit into correspondingnotches 18, formed in the upper edges of the standards 10. (See Fig. 2.)Each standard is provided with a swinging hook 19, which hooks arerespectively adapted to engage eyes on the side edges of the plate 16,and thus hold the plate down on the standards 10. These hooks '19, withthe studs 1? bearing in the recesses 18, serve rigidly to hold the topplate 16 and also to brace the frame structure formed by the standards10. The top plate 16 is removable for the purpose of locating anddisplacing the various devices contained in the frame, as will behereinafter described.

Mounted in suitable bearings in the standards 10 and running between thestandards is a shaft 20, which carries in the form of a roll the web ofpaper 21. Beneath the roll of paper a transversely-extending water-tank22 is arranged and rests on the plate 9. This tank carries a glassroller 23, which extends from end to end of the tank and beneath whichthe web of paper passes. The rear side of the tank 22 has an upwardlyand rearwardly extending lip 24, forming a shield to catch splashedwater. The front side of the tank 22 has an extension 25,which passesupwardly and forwardly to the front of the machine and is there restedon a bar 26, passing between and connected with the standards 10. Thisextension 25 serves to catch the water that may drip from the web ofpaper after it has been submerged in the tank 22 and to return the waterto the tank. The paper drawn from the roll passes down beneath theroller 23 and through the tank, where it is impregnated with the water,and then is drawn up over the extension 25.

For drawing the paper 21 from the roll and for pressing it against theoriginal to be copied I provide three rubber rolls 27, 28, and 29. Theroll 27 has the ends of its shaft 30 mounted in hearings in thestandards 10, such bearings being formed by slide-plates 31, removablyheld in position by means of screws, as shown in Fig. 1. Theslide-plates are two in number, arranged one at each end of the shaft30. The roller 28 is arranged slightly above and in contact with thefront side of the roller 27 in such a manner that the web of paper 21may pass between the rollers 27 and 2S,which rollers serve to draw thepaper forward and to press therefrom'all superfluous water,which wateris taken up by the extension 25 and led back to the tank. The ends ofthe shaft 32 of the roller 28 are respectively mounted in the standards10 in bearings formed by the plates 33, which are carried, respectively,at the ends of the block 34 and which serve the double purpose ofholding the block in place transversely at the front of the roll 28 andalso of mounting the ends of the shaft 32. This block 34 and its plates33 are shown in detail in Fig. 6,wherein it will be seen that each plate33 is provided at its inner face with a rib 35,which ribs are designed,respectively, to slide in grooves formed in the standards 10, and theplates 33 are held in place by screws, as shown in Fig. 1. The block 35has a sharp upper edge lying slightly below the upper side of the roll28 and in close proximity thereto, so that the web of paper in turningwith the roll 28 will be separated from the roll and prevented fromclinging thereto. The block 34 may also be used as a straight edge onwhich to tear off portions of the web of paper.

The roll 29 is mounted in supplementary standards 36, rising,respectively, from the standards 10. The ends of the shaft 37 of theroll 29 are held in bearings, each formed by a block 38, (see Fig. 1,)which blocks slide in the upper ends of the standards 36 and are heldadj ustably by screws 39, in turn carried in plates 40, made fast byscrews to the upper ends of the standards 36. By these means the roll 29may be mounted to turn with greater or less friction, as may be desired.To the right-hand end of the shaft 32 is fixed a crank-arm 41, carryingahandle 42, by which the roller 28 may be turned. This roller contactingwith the rollers 27 and 29 causes all of the rollers to turn in unison.The paper is drawn from its roll by means of the rollers 27 and 28, andthe copying is effected by passing the original from which thereproduction is to be made face downward between the rolls 2S and 29 andabove the paper 21, so that the compressive action of the rollers 28 and29 on the two thicknesses of paper will effect the reproduction. Theoriginal may be passed through the press repeatedly and with greatrapidity, thus producing any number of copies.

Should a great number of copies be taken from a single original, thereproductions will be produced on a continuous web of the paper 21,which should afterward be severed into sections, according to the copiesthereon. This is effected by the cutting device which forms a part of myinvention and which is shown in detail in Figs. 4 and 5. Mounted at therear end of the top plate 16 and lying on the same is the bed 43 of thecutting device. The right-hand end of the bed is provided withdownwardly-projecting studs 44, which are seated in orifices formed inthe top 16. The left-hand end of the bed 43 is provided with adownwardly-projecting extension 45, which lies against the outer face ofthe left-hand standard 10 and which is provided with two studs 46,projecting into orifices formed in the standard. Rising from theleft-hand end of the bed 43 are two lugs 47, which carry the pivot of aknife-bar 48, which is mounted to swing toward and from the bed 43 andhas a handle 49 of any desired construction at its free end. Theknife-bar 48 coacts with a stationary or bed knife 50, which is carriedrigidly on the bed 43. By raising and lowering the knife-bar 48, asindicated by dotted lines in Fig. 4, the cutting device may be made toact, and the web of paper 21 may be readily severed into sections of anydesired number and size.

In order to conveniently fill the tank 22, I provide a funnel, as shownin Fig. 7, which has a body 51 and a spout or nozzle 52, the body beingbent diagonally, so as to bring the spout at one side and permit it tobe passed through an orifice in one of the standards 10, so that thespout will lead properly to the tank and avoid spilling the liquid.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A copying-press having a frame, a roll having theends of its shaft mounted in the frame, a block extending along one faceof said roll and serving to separate a web of paper therefrom, andplates carried at the ends of the block and engaging the ends of theshaft of the roll to hold the roll in place.

2. A copying-press having a frame, a shaft mounted in the frame andadapted to carry a roll of paper, a trough mounted on the bottom of theframe, a roller in the trough and serving to submerge the web of paperfrom the roll in the trough, two feed-rollers be tween which the webpasses and by which the web is drawn from the roll, an additional rollerbearing down upon one of the feedrollers to impress the copy on the web,a block having a tapered edge engaging the outer feed-roller to separatethe moistened web from said feed-roller, and a plate carried at each endof the block, and engaging the ends of the shaft of said outer feed-rollto hold the said shaft in place.
